Good day! I'm new here and this is my first post and I really do wish someone can advice or guide me for my new career path. Ok, right now I have the certification in network security and now in the midst of studying the python programming.

I thought of if I can master in python programming, I would able to create a Network Security Application using Python, embed it on the (client / customer's) website. Meaning their daily application, all their transactions, informations and so on will be strictly within their organization and dealing with other company will be encrypted/decrypted. Or you have better idea which path I should look ahead further to? Please feel free to advice. Thank you. Have a pleasant day!

So like are you talking about a SIEM (Security Information and Event Monitoring) app? Not sure what you want to actually build. Network Security is a fairly broad topic. Also Python might not be the best tool for a web based app. Need a bit more information as to what you are looking for.
